Endoscopic hemostatic clipping apparatus
First Claim
1. An apparatus for applying clips to tissue, comprising:
- a plurality of clips linked to one another to form a clip chain;
a control linkage coupled to a proximal-most one of the clips for applying tension and compression to the clip chain; and
a magazine containing the clip chain, the magazine including an abutment surface sized to permit passage distally therebeyond only of a distal-most clip of the clip chain, the clips being biased so that, when a distal-most one of the clips is moved distally out of the magazine, arms of the distal-most clip move apart to a tissue receiving configuration, a distal opening of the magazine being shaped so that, as the distal-most clip is drawn back into the opening through the application of tension to a proximal-most clip of the clip chain, the clip arms of the distal-most clip are drawn together to grip tissue received therebetween.

Abstract
An apparatus for applying clips to tissue, comprises a plurality of clips, each of the clips including a proximal end having a pair of opposed jaws and a distal end including a linking feature, where the clips are linked to one another to form a clip chain with a linking feature of a distal-most one of the clips being gripped between the jaws of an immediately proximal one of the clips and a control linkage coupled to a proximal-most one of the clips for applying tension and compression to the clip chain in combination with a magazine containing the clip chain, the magazine including an abutment surface sized to prevent passage distally therebeyond of a clip having received between its jaws a linking feature of an immediately distal clip and an opening location within which the jaws of a clip are permitted to open to release a linking feature therefrom.

8. An apparatus for applying clips to tissue within a body, comprising:
-
an elongate body extending from a proximal end which, when in an operative position, remains outside the body to a distal end which, when in the operative position extends into the body to a location adjacent to a target portion of tissue to which one or more clips are to be applied; a control element extending through the elongate body to the distal end thereof; and a magazine formed at the distal end of the elongate body, the magazine housing therein a chain of clips with a proximal-most one of the clips being coupled to the control element to transmit a compressing force and a tensioning force applied by the control element to the clip chain, each of the clips including a pair of opposed jaws moveable between open and closed positions, the magazine further including a clip limiting feature distally past which only a distal-most one of the clips may pass, a relief portion of the magazine permitting separation of the most distal clip from the clip chain when the distal end of a clip immediately proximal to the distal-most clip is located therein, the clips being biased so that, when a distal-most one of the clips is moved distally out of the magazine, arms of the distal-most clip move apart to a tissue receiving configuration, a distal opening of the magazine being shaped so that, as the distal-most clip is drawn back into the opening through the application of tension to a proximal-most clip of the clip chain, the clip arms of the distal-most clip are drawn together to grip tissue received therebetween. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method of deploying hemostatic clips, comprising:
-
inserting to a target site in a body a magazine including a plurality of hemostatic clips connected in a clip chain, each of the clips including a pair of opposed arms; translating the clip chain distally to extend a distal-most one of the clips out of a distal end of the magazine to open the clip arms of the distal-most clip into a tissue receiving configuration; positioning the distal-most clip to receive a first target portion of tissue between the clip arms thereof; translating the clip chain proximally to draw the distal-most clip back into the magazine and close the clip arms of the distal-most clip over the first target portion of tissue, the translating being performed by applying a tensioning force to a proximal-most clip of the clip chain; translating the clip chain further proximally to detach the distal-most clip from a next most distal clip of the clip chain; and moving the magazine to a second target location to deploy the next most distal clip over a second target portion of tissue. - View Dependent Claims (22, 23, 24, 25)
